Profiles

Who we work with. Recurring counterparties.

On projects we develop ourselves we deal with landowners, industrial offtakers and investors. On advisory we work with owners of stalled projects, with those who own operating plants or are considering buying them, with public bodies promoting a renewable energy community (CER) and with energy service companies (ESCos).

Seven profiles, seven different conversations. For each one: what is usually needed, what we do, what to have ready for a first contact, and where to read more.

Last reviewed:

I have land

Landowners

Owners of agricultural or industrial land, or of a building roof, who want to know whether it can host a solar photovoltaic plant. On projects we develop ourselves we deal with landowners directly: the development phase starts from a piece of land.

Get in touch

We reply within two business days.

What is usually needed

  • Whether the area is suitable: planning, landscape and grid constraints
  • A clear title on the area: surface rights or a lease
  • Clauses that hold up beyond the incentive period
  • What happens after signing: permitting and grid connection

What we do

  • Planning, landscape and grid checks on the area
  • Agreements with the owner, as surface rights or a lease
  • Permitting and the grid connection request on the projects we develop
  • Engineering and legal partners, brought in when needed

What to have ready for a first contact

  • Municipality and approximate size of the area
  • Current use: agricultural, industrial, building roof
  • Who owns it, and whether there are other title holders
  • Known constraints and, if available, the zoning certificate (certificato di destinazione urbanistica)

I need energy for my company

Offtakers

Businesses that consume electricity and are considering covering part of it from renewables: through a power purchase agreement (PPA), a self-consumption plant or by joining a CER. On projects we develop ourselves the offtaker is the counterparty to the PPA.

Get in touch

We reply within two business days.

What is usually needed

  • Comparing the routes: PPA, on-site or remote self-consumption, CER
  • A price and delivery structure that fits the consumption profile
  • Clarity on who bears price risk and profile risk

What we do

  • Reading the consumption profile and the sites to choose the structure
  • PPA structuring: term sheet and main terms
  • On the projects we develop, the PPA or CER configuration is structured from the design stage

What to have ready for a first contact

  • Annual electricity consumption over the last few years
  • Hourly or monthly load data, if available
  • Number and location of the withdrawal points
  • Current supply contract and its expiry
  • Space available for an on-site plant, if any

I have a stalled project

Stalled projects

Solar projects stuck halfway through development: a permit that does not come, an onerous grid connection solution, a missing energy buyer, financing that does not close. The starting point is the documents, to see where the project stopped and why.

Get in touch

We reply within two business days.

What is usually needed

  • Understanding where and why the project stopped
  • A second read of permitting, grid connection and business case
  • A deal structure that holds: project company (SPV), energy sales, financing
  • The next steps, in order, with their conditions

What we do

  • Review of the permitting process and of the documents filed
  • Check of the grid connection solution and of the commitments it carries
  • Review of yield and business case
  • Deal structure: SPV, energy sales, financing

What to have ready for a first contact

  • Permit, or status of the application, with the key dates
  • Grid connection quote and whether it has been accepted
  • Land agreements and their expiry dates
  • Latest business plan or financial model
  • Where it stopped, since when, and what has already been tried

I invest in Italian solar

Investors

Infrastructure funds, family offices and industrials entering Italian solar. They want due diligence (DD) done by people who develop and structure plants, not only analyse them.

Get in touch

We reply within two business days.

What is usually needed

  • Buyer-side technical and regulatory DD
  • Bankability for project-finance structures
  • Portfolio consolidation across heterogeneous data rooms
  • Post-closing integration and first 100 days

What we do

  • End-to-end acquisition-side DD, one point of contact
  • Access to AIP Engine for structured dossiers (early access, by referral)
  • Technical input to conditions precedent
  • Post-closing support to the asset manager

What to have ready for a first contact

  • Scope of the deal: number and approximate capacity of the assets
  • Asset stage: development, ready to build, operating
  • Data room index or access arrangements
  • Deal timetable: offer, signing, closing
  • Scope of the DD: technical, regulatory, contractual

I represent a public body

Public bodies and local authorities

Municipalities and authorities that want to set up a CER. The law admits local administrations on the ISTAT list as members; less structured municipalities, however, often lack the skills in-house.

Get in touch

We reply within two business days.

What is usually needed

  • Promoting the CER: governance, statute, distribution
  • Verifiable rules for distributing the incentive
  • Engaging residents, businesses and other local stakeholders
  • Compliant, financeable tenders

What we do

  • CER design: structure, governance and allocation rules
  • Support in preparing tenders and framework agreements
  • Engagement programmes for residents and businesses
  • We build CER-Ops, software for those who run a CER, in its launch phase, with invitation-only access; management stays with the referent

The referent (Soggetto Referente)

Under the GSE rules the referent of a CER may be: the community itself, through its legal representative; a producer member; a final-customer member; a third-party producer that is not a member and has a plant in the configuration, if it is an ESCo certified under UNI CEI 11352.

ARERA's integrated text on distributed self-consumption (TIAD) allows the community to give another party a mandate without representation: one year, tacitly renewable, revocable at any time.

Altheon is not an ESCo, holds no UNI CEI 11352 certification and does not take on the role of referent.

Sources

What to have ready for a first contact

  • Objective: promote a CER, join an existing one, self-consumption on public buildings
  • Public buildings or land available, and approximate consumption
  • Acts already adopted, such as policy resolutions or public notices
  • Grants applied for or open calls, with their deadlines

How energy moves in a renewable energy community (CER)

Three layers, read in order: the grid, the hour-by-hour calculation, the incentives.

  • Energy fed in
  • Energy withdrawn
  • Shared energy
  • Premium tariff, contribution and allocation
  • Primary substation area
  1. The grid. The plant feeds energy into the distribution grid; members withdraw from the same grid. To access incentives and tariff refunds, plants and consumers must be connected under the same primary substation (Legislative Decree 199/2021, art. 31). The areas served by primary substations are conventional: distribution operators define them and the GSE publishes them (TIAD, art. 1 and art. 10).
  2. The hourly calculation. In each hour, shared energy is the lower of the energy fed in and the energy withdrawn for sharing purposes by the configuration's points in the same market zone (TIAD, art. 1, letter t). The part relating only to points under the same primary substation is self-consumed energy, the basis of the valorisation contribution (TIAD, art. 1, letter r). Since 24 January 2026 the law defines shared energy over periods of up to one hour (Legislative Decree 199/2021, art. 2); ARERA is aligning its rules (resolution 223/2026/R/eel).
  3. The incentives. The GSE pays the premium tariff (TIP) on the share of energy shared under the same primary substation, together with the valorisation contribution (Ministerial Decree 414/2023, art. 4). It pays them to the Referent (Soggetto Referente), the GSE's contractual counterparty (GSE, configurations page); in a CER the referent is the community itself, which may give a mandate to another party (TIAD, art. 1, letter hh). Participants name, in a private-law contract, the party responsible for allocating the shared energy (Legislative Decree 199/2021, art. 32). The energy fed in stays with the producer, who sells it on the market or to the GSE under dedicated withdrawal (Ministerial Decree 414/2023, art. 4). The GSE pays the tariff as an estimated monthly advance with a true-up on actual meter data (GSE operating rules, para. 2.2.2.1.2).

Hour by hour

Illustrative profiles of one day: shapes, not measurements of a real plant or community.

  • Shared energy (the hour's minimum)
  • Fed in beyond withdrawals
  • Withdrawn beyond feed-in

From 13:00 to 14:00: feed-in exceeds withdrawals: shared energy equals withdrawals, the rest is fed in without being shared.

I work at an ESCo

ESCos

ESCos whose CER portfolio is growing faster than their in-house resources. We come in as advisors on specific pieces of the chain.

Get in touch

We reply within two business days.

ESCos that want to join the partner network we work with on projects can apply from the Partners page.

What is usually needed

  • Bid and tender support on tight timelines
  • CER statutes and architectures across several initiatives
  • Bankability work and permitting
  • Specialist skills without a permanent hire

What we do

  • Advisory on CER and bankability, in support of the ESCo's own offers

ESCos and the referent role

Under the GSE rules a third-party producer that is not a member, with a plant in the configuration, may act as the CER's referent if it is an ESCo certified under UNI CEI 11352. Altheon is not an ESCo and holds no UNI CEI 11352 certification.

What to have ready for a first contact

  • Type and approximate number of initiatives: CERs, groups of self-consumers, remote self-consumption
  • Scope of support: statute, bankability, permitting, due diligence
  • Bid or tender deadlines
  • The ESCo's role in the configuration: producer, referent, service provider
